charging opening of the mixer, so as to receive the said aggregates from barrows or shovels, or any other manner, near the ground level, and are provided with means Ior elevating them; The loader is usually so mounted that as it is raised it also tips or tilts and mixer. A common arrangement is to have 1 it mounted on a pivoted arm or frame, and the present improvements are designed to securea better mounting and operation of a loader so mounted, and to economize the power required to elevate it with itsload.

he improvements are illustratedinthe accompanying drawings, in which Fig. 1 is a side elevation of 'aloading bucket with connected parts embodying the improvements V Fig. 2 is a similar view with the bucket raised to discharging position;

Fig. 3 is an end view of some of the parts looking from a point inside the mixer frame, I v Fig. at is a diagrammatic view ofa detail.

The operation of the device is as follows.

The bucket receives its load in the position shown inFig. 1, and-then is raised by'the cable 2.

The parts then swing on the pivot 7 until the bucket reaches the position illustrated in Fig. 2, where it dis charges its. loading into the mixer. It will of pull of. the cable 2 is substantially tangential to the are described by the bucket carrying frame'untilthe bucket reaches an position a comparatively short one requiring a mini- The further inward and .upward swing. of the bucket is aided by the movement of the materials toward the discharge end.

y The pivot? is in the form of a rod run 7 ning through the turnedsides of the member and the brackets 8, and the pivot 9 is simiiar or shorter bar extending through-- the sides of the member 6 in like manner and through. theplate 10 of the pivoted bucket carrying frames. One' of these :also relatively short and JERSEY, ASSIGNOR TO RANSOME CONCRETE 'lhiscausxs it to pivot on the axis .beseen that by this arrangement the line" frames is located on each side of the member bucket. The member (i is preferably in the .form of a plate of heavy sheet metalwith as J desired. The form shown, however, has the advantages of strength, simplicity and easy of assembling. The check member 16 extends across from one member 11 to the other, and forms a brace as well as a stop. It comes in contact with the pivot bar 7 between the edges of the outwardly turned sides of the part 6 when the bucket reaches the position of Fig. 2. Another feature of the movements consists in the manner of running the cable 2 and connecting it with the bucket. This cable runs over a sheave on each side of the frame at the top and through a bale 23 entering the bale at one side of the bucket extending around under it and passing out at the other side. The bale is connected with the bucket by a pivot Q/f'on each side so that there is a certain amount of. pivotal movement between the two parts. This equalizes the pull of the cable on the bucket, and also protects the cale' against undue wear and injury or the deteriorating eiiect of exposure to the ground, as where it is run under the bucket.

A diagrammatic view of the parts'mentioned is shown in Fig. l. i

hat I claim is:

1. In a device of the character described, a supporting frame, a loader bucket having charging and discharging portions at an angle to each other, means for elevating same comprising a cable attached to the bucket and extending to the upper part of the frame and a source of pow 1' connected with said cable, a member pivotally mounted on said frame and extending downwardly therefrom, and a second member pivoted to the lower portion of the first member and extending laterally therefrom to the bucket when the said bucket is in loading position, said member composed of parts extending from the pivot on divergent lines secured to the bucket at different points, a jaw shaped member mounted on said second member and positioned for contact with the-pivot of the first named member for supporting said bucket in its finalarcnate travel,- the construction and arrangement being such that the bucket in rising first moves on the pivot of the second member to a position in which its outer portion is above horizontal position and its inner or discharging portion is in approximately horizontal position, and then swings inwardly and upwardly on the pivot of the first and downwardly extending member.

2. In the device specified in claim 1, a stop on the frame limiting the movement of the first-named member away from its bucket elevating position and a check memb'er extending from the second member and adapted to come in contact with the pivot of the first member on the upward movement of the former.

3. In the device specified in claim-1, the

said first member consisting of a plate having turned edges, extending substantially from side to side of the bucket.

l. In the device specified in claim 1, the said elevating means being connected with the bucket at a medial point and opposite the second pivoted member.

5. In the device specified in claim 1, a

portion of the second pivoted member bcwith said cable, a member pivotally mounted on said frame and extending downwardly therefrom, and a second member pivoted to the lower portion of the first member and extending laterally therefrom to the bucket when the said bucket is in leading position, a jaw shaped member mounted on said second member and positioned for contact with the pivot of the first named member for supporting said bucket in its final arcuate travel',-. the construction and arrangement being such that the bucket in rising first moves on the pivot of the second member to a position in which its outer portion is above horizontal position and its inner or discharging portion is in approximately horizontal position and then swin 's 1n-.

wardlyand upwardly on the pivot of the first and downwardly extending member.

7. he combination with a mixing vessel and a frame for supporting the same, of a loader bucket for the mixingvessel, means for pivoting said bucket with reference to the frame consisting of a pendentlyhinged link, said link having a hinged connection at its free end with the loader bucket, said hinged connection having a jaw member positioned to engage the hinge of said link for supporting the loader bucket during final travel to charging position, and means for raising the bucket first on the lower axis and then on the other to mixing vessel charging position.

8. The con'ibination with a mixing vessel and a frame for supporting the same, of a loader bucket for the mixing vessel, means for pivoting said bucket with reference to the frame consistin of a pende'ntly hinged link to oscillate from one side of a vertical line from its hinging axis to the other, said link having a hinged connection at its free end with the loader bucket, said hinged connection having a aw member positioned to engage the hinge of said link for supporting the loader bucket during final travel to charging position, and means for raising. the

on the lower axis and then on the other to mixing vessel. charging position.

9. The combination with a mixing vessel. :2 d a frame for supporting the same, of a loader bucket for the mixing vessel, means for pivoting said bucket with reference to the frame consisting of a pendently hinged link, said link having a hinged connection at'its free end with the loader bucket, said hinged connection having a j aw member positioned to engage the hinge ofsaid link for supporting the loader bucket during final travel to charging position, and means for raising the bucket first on the lower axis and then on the other to mixing vessel charging position and a stop for limiting the swing of said link at its innermost position.

10. The combination with a mixing vessel and a frame for loader bucket for the mixing vessel, means for pivotallysupporting said bucket for swinging through diiierent arcs comprising :1 depending link having a pivot connecting it at its upper end to said frame, a frame fixed to said bucket and having a pivot connecting it with the lower portion of said link, a supporting jaw on said last named frame, the distance between said jaw and second pivot being substantially equal. to the distance between said pivots, and means for swinging said bucket in an are about said second said first pivot and thence for swinging said bucket in an are about said first pivot while said bucket is supported thereon by said aw.
